After thinking a bit about Fabio's recommendation to use 'read-only'
to protect the partitions, I think it'd be better to use 'lock' so it
is still possible to write them on Linux but it requires a unlock
prior changing it.

In my case, I am interested in being capable of upgrading the
bootloader from Linux.

What people think?
